For many years, I'm wearing, recommended by a medical supply store, the competitor: Chung Shi DUX Clogs and as flip-flops. Very comfortable, very soft, slightly spongy. Then I bought, even at Amazon, the Winterclog from the same house. And the trouble began. Then I received from a friend recommending the crocs Blitzen II. Said and done or ordered. Then came the crocs; first impression very good. Rein hatched and fit. Then in the evening directly carried to the dog walk. WOW !!! Everything that had bothered me the competitor is perfectly solved with crocs Blitzen II. The food stays where it is and belongs, the shoe is soft but not spongy, one feels while running safely. Consequence:'ve ordered now a second pair, for testing my wife right one too, and the Chung Shi DUX walk to the flea market. I can see the crocs Blitzen II highly recommend. A great shoe or clog. Convenient goes Nimmer's. Genial. I am now convinced crocs fan and support.
